Yep. Thanks, it has been a long night.

Homework Statement Prove: \lim_{x \to a} \sqrt{x} = \sqrt{a}, if a>0 Homework Equations |f(x)-L| < \epsilon |x-a| < \delta The Attempt at a Solution |\sqrt{x}-\sqrt{a}| < \epsilon, when |x-a| < \delta |x - 2\sqrt{x}\sqrt{a}-a| < \epsilon^2, when |x-a| < \delta From here I...
